Title: Condensation of evaporated liquefied natural gas - convertible to petroleum gases by driving refrigerant turbo-compressor stages separately
Inventor: ETZBACH VOLKER DIPL ING
IPC: F25J1/02
Filed: 1974-12-04
Abstract: A refrigeration circuit with turbocompressors which has been designed for the condensation of LNG (liquefied natural gas) can be converted for the condensation of LPG (liquefied petroleum gases) if the individual compressor stages are driven separately from each other. Only certain compressor stages of the refrigeration circuits are used for the compression of the nitrogen normally used as the circulating medium. Turbocompressors must not have a flow rate below their surge point which would necessitate the useless recirculation of nitrogen when LPG is to be condensed. This waste of energy is saved, also the starting current of smaller compressor is smaller than that of one big motor.
